Application filed August 29, 1916.

To all whom it may concern:

Be it known that I, Gnonon C. Hnsrnn, a citizen of the United States,and resident of Chicago, in the county of Cook, and in the State ofIllinois, have invented a certain new and useful Improvement in Cornerand Division Bars for Store-Front Constructions, and do hereby declarethat the following is a full, clear, and exact description thereof.

In the well-known plate glass store front construction, what are knownin the trade as corner and division bars are employed at the verticalcorners and other division points in the front between adjoining platesof glass, to secure them in position thereat. The angles of the platesof glass that form the corners, greatly vary, and while ,attempts havebeen made by others to provide a corner bar construction that would beadaptable to various angles, yet as far as I know to the contrary, theattempt has never succeeded, but the present practice is to provide adifferent corner bar for each angle. This requires a great assortment ofcorner bar angles, and even then difficulties arise because of failureof a particular corner bar and the glass plate as installed, toaccurately agree, through error or carelessness of workman. Such lack ofagreement results in failure of proper support be given the glass, anddanger of breaking it by forcing an agreement. The object of myinvention is to provide a bar construction which will have suchflexibilty or scope of adjustment that the same bar will suit any anglerequired, and,-if desired, even to the extent of an angle of 180,degrees, so that a great variety of corner bars and separate divisionbars, as such, is not necessary, but the one construction will serve allpurposes and efficiently and with entire practicability meet allrequirements. Other objects and advantages of my invention will beunderstood by those skilled in the art when the embodiment of suchinvention shown in the drawings, is more fully explained in thefollowing specification, of which said drawings form a part.

My bar, briefly described, comprises as I the necessities of the caserequire, glassengaging members in the form of duplicate pairs ofvertical rails, between which, and the adjacent edges of adjoiningplates of glass, clamping bolts or screws are passed, by which the railsof a pair, situated, respectively, on opposite sides of the same plateof glass are caused to exert the desired clamping pressure thereon.These rails are made of sheet metal, such as copper, of sufficientthinness to enable great lengths thereof readily to be bent or shapedinto the desired form in cross section.

In the form of my invention shown in the drawings, the inner and outermembers of each pair of rails are pivoted to each other on alongitudinal axis and the corresponding parts of the opposite pairs arepivotally connected on such an axis so that the two members of acooperating pair, which for convenient designation I shall term plates,may be spaced apart a distance corresponding with the thickness of theplate of glass 10 to be engaged thereby, one of which plates 11 is onthe outer side ofthe plate 10, and the other plate 12 is on the innerside thereof, and their pivotal connection with each other and with thecorresponding members of the other pair lies in the space between theedges of the two adjoining plates of glass and all four plates beingprovided with a flat glass-em gaging portion which is the outer part ofthe plate and a concavo-convex curved portionthatreachesfromtheflat,orplaneportion to'the pivotal connection between the plateswhich may readily be formed by a more or less complete tubular portionon the inner edge of each plate, the various tubular portions being ofdifferent diameter so that one may be applied to the other in aconcentric arrangement, the innermost one being a complete round tube.By the pivotal connection thus formed, each pair 0 plates may and innerglass-engaging plates of a pair toward each other to clamp the plates ofglass therebetween, comprising a bolt, a clip with which the bolt isconnected that straddles the flexible connection between the pair ofouter plates, and a bar outside of the outer plates with which said clipis connected.

3. A glass clamping device comprising two pairs of glass-engaging platesthat respectively engage outer and inner sides of the plates of glass,the plates of a pair being flexibly connected with each other, and thetwo pairs being flexibly connected together at a point between the twoplates of glass to be held, and the inner pair of plates having a lipand slot connection, and means for drawing the outer and innerglass-engaging plates of a pair toward each other to clamp the plates ofglass therebetween.

4. A glass clamping device comprising two pairs of glass-engaging platesthat respectively engage outer and inner sides of the plates of glass,the plates of a pair being flexibly connected with each other, and thetwo pairs being flexibly connected together at a point between the twoplates of glass to be held, and means for drawing the outer and innerglass-engaging plates of a pair toward each other to clamp the plates ofglass therebetween, comprising yieldable arms that engage the respectiveinner plates, and a stop to limit the movement of said arms toward eachother.

5. A glass clamping device comprising two pairs of glass-engaging platesthat respectively engage outer and inner sides of the plates of glass,the plates of a pair being Copies of this patent may be obtained forflexibly connected with each other, and the two pairs being flexiblyconnected together at a point between the twoplates of glass to be held,and means for drawing the outer and inner glass-engaging plates of apair toward each other to clamp the plates of glass therebetween,comprising a bar having yieldable arms that bear against inclinedsurfaces on the respective inner plates, and a stop on each of saidinner plates adjacent said arm.

6.. A glass clamping device comprising two pairs of glass-engagingplates that respectively engage inner and outer sides of the plates ofglass, a flexible connection between said pairs of plates, and means tocause the opposite plates of a pair to clamp an interposed plate ofglass, said pairs of plates being self-adjustlng on the flexibleconnection between them to conform to the angular relation of the platesof glass.

7. A glass clamping device comprising two pairs of glass-engaging platesthat respectively engage outer and inner sides of the plates of glass,all of said plates being pivotally connected to each other on a commonaxis, means connecting the plates of each pair to enable them to behandled as a unit while permitting rocking movement of the plates upontheir pivotal connection, and means for drawing the outer and innerglass-engaging plates of a pair toward each other to clamp the plates ofglass therebetween.

In testimony that I claim the foregoing I have hereunto set my hand.

GEORGE C. HESTER.
